History & Status of the Fishery
Slate Lake is a 293 acre lake with a maximum depth of seven feet located along State Highway 1 northwest of Isabella. The Stony River flows through the lake and access is gained via the river channel below the lake outlet. Anglers then paddle or motor upstream from the access into the lake. There are many rocks that are difficult to see in the dark water and a shallow rocky riffle between the access and the lake that can be hazardous to motor boats.
Spring trap netting was completed on Slate Lake during early June of 2022 to gather information on the Bluegill population that was first detected in the lake in 1999. A total of 89 Bluegill were sampled, almost twice as many as sampled in the 2019 survey, and a good number for this area. Size structure remained good with 56 percent of the sample longer than eight inches and the longest fish measuring over 11 inches. Bluegill ranged from two to eight years old with each year class represented indicating consistent reproduction in recent years. The population will continue to be monitored because the lake is one of only a few in the Finland Area that supports a fishable Bluegill population with opportunities for anglers to potentially catch a memorable fish.
Slate Lake has a diverse fish community with a variety of sportfish populations available to anglers. Walleye, Northern Pike, Smallmouth Bass, Pumpkinseed Sunfish, Rock Bass, White Sucker, and Yellow Perch were also sampled during this survey.
